SYNTHESIS and CHARACTERIZATION of FUNCTIONALISED SILICON PHTHALOCYANINES for FABRICATION of SELF-ASSEMBLED MONOLAYERS

Zhiyong Li and Marya Liebeerman

Dept. of Chemistry and Biochemistry, University of Notre Dame, Notre Dame, IN 46556, USA

[Abstract] We are interested in using the self-assembled monolayer (SAM) deposition technique to form ultrathin films of well-oriented silicon phthalocyanine derivatives 1a and 1b have been designed. Both molecules contain thiols to anchor the phthalocyanine to a flat gold surface. In 1a, the thiol is on a short alkyl chain attached to the central silicon atom, while in 1b, eight thiols are arranged around the peripery of the phthalocyanine ring. In each case, the anchoring group or groups are disposed so the phthalocyanine rings will sit flat on a gold surface, rather than lie tilted. The eight alkyl chain substituents on each ring will serve both to increase the solubility of the phthalocyanine in organic solvents and to act as spacers when the phthalocyanine molecules are attached to a surface.

The phthalocyanines are synthesized by an elaboration of literature methods. Derivatives of diiminoisoindoline are condensed with silicon precursors such as RSiCl₃. The sulfhydrl group or groups can be added either to

the diiminoisoindoline or to the silicon trichloride by incorporating a vinyl group or groups into either molecule. Free-radical addition of thiolacetic acid across the double bond yieds the thiolacetate in nearly quantitative yield, and the thiol may be revealed by base hydrolysis. The intensely colored green phthalocyanine compounds are soluble in chloroform, benzene, and toluene in millimolar concentrations.

We will report the details of the synthesis and characterization of 1a and 1b by UV-Vis, IR, and NMR spectroscopy. The electrochemistry and photochemical stability of 1a and 1b, which bears on their potential utility in electronic or photonic devices, will be discussed, as well as some preliminary work on SAM formation by these molecules.

Neural Networks Based on Biomolecular Nonlinear Dynamic Media : State of Art and Some Potentialities

Nicholas G. Rambidi

International Research Institute for Management Sciences

[Abstract] The information processing capabilities of biomolecular excitable media based on nonlinear dynamic mechanisms are discussed. The dynamics and information processing features inherent in biomolecular excitable media proves to be divers and sophisticated even in the simplest medium geometry. For the case of pseudo two-dimentional implementations these media can be compared to neural networks having laterial connections. The main responses to external excitations given by shunting on-center off-surround feedback neural networks and pseudo-two-dimentional excitable systems are surprisingly similar. Excitable media are capable of short-time memory, of contour enhancement, and of quenching or amplifying small features depending of medium state. The analogies discussed highlight specific neural net characteristics of excitable media and make it possible to more accurately estimate some excitable medium characteristics.

Raman scattering characterization of nanophase titanium dioxide

Wenhui Ma, Zuhong Lu

Recently, nanocrystalline TiO2 has attracted much attention due to their improved properties and numerous potential applications including nanoporous solar cell, photocatalyst and optical coatings, etc. [1-3]. The technological applications of nanophase TiO2 has aroused considerable interest in the structures and phase transformations [4-6]. It was suggested by x-ray diffraction studies that the nanophase materials exhibited neither long-range order nor short-range order, while Raman scattering studies showed that crystalline structure existed in the nanophase [4]. Raman spectroscopy is an important structural probe and is very sensitive to the onset of structural transformations, it has been used to investigate the first-order vibrational spectra of anatase and rutile phases of polycrystalline titanium dioxide [7]. In this letter, we would like to report the Raman spectroscopic study of nanocrystalline TiO2.

RROTEIN ENGINEERING FOR SELF-ASSEMBLING PROTEIN MOLECULAR NETWORKS ON SOLID SURFACE

Masuo Aizawa, Shigeya Suzuki, Kyushik Yun, Tetsuya Haruyama, Yasuko Yanagida, and Eiry Kobatake

[ABSTRACT] Two types of protein engineering have been developed for fabricating protein molecular networks on the solid surface. The first is to tag a cystein group to Protein A. The cystein-tagged Protein A molecules were self-assembled on the gold surface, which was followed by self-assembling of IgG antibody in an oriented manner. The second is concerned with tailing a single chain antibody by lipid at the one terminal and hexahistidinyl group at the other terminal. The lipid and histine-tailed single chain antibody was embedded in a liposome, which was immobilized on the Nitreated mica surface. The individual liposome was clearly imaged by a tapping mode of AFM

A JORDAN ONE IS BEHIND THE VAN HOVE SCENARIO. TOWARDS A QUANTUM CHEMICAL THEORY OF HIGH TEMPERATURE SUPERCONDUCTIVITY.

GEZA BICZO Central Research Institute of Chemistry, Hungarian Academy of Sciences, H-1525 Budapest 114, P.O.Box 17, Hungary; E-mail: biczo@cric.chemres.hu

Several published observations are discussed to support this idea. The draft of a quantum chemical theory is given for a more complete verification.
